Silliness involving politics aside. Here's my view on things: each faction is all over the map, for example, in the outcasts, we have the Viks, who are but a single event away from being the heroic fantasy character archetype, and Leveticus, a steampunk necromancer, someone widely considered incredibly evil.
A better choice would be The Guild, who have the Death Judges, an in-arguably good force, then there's the rest of The Guild, who are a bunch of dirt-bags, at best.
Some portions of the Neverborn are jerks, look at the ones who attacked Viktoria, inevitably giving her a Doppelganger, and then there's Lilith, the leader of the Neverborn, who is just trying to get rid of these human invaders, but she's also willing to work with them if it means keeping the Tyrants down.
